Inventor: MCWILLIAMS KEVIN RONALD
IPC: H01H37/48
Filed: 1992-01-23
Granted: 1994-11-02
Abstract: A device for controlling or limiting temperature in an electric cooking appliance comprises a switch (44) and a temperature sensor (42) operatively coupled to the switch. The temperature sensor comprises a rod (46) arranged substantially coaxially within a tube (52), the rod being made of a material having a first coefficient of thermal expansion and the tube comprising at least two tube portions (48, 50), one of the tube portions being made from a material having a second coefficient of thermal expansion lower than the first coefficient of thermal expansion and another of the tube portions being made from a ceramic material having a third coefficient of thermal expansion intermediate the first and second coefficients of thermal expansion. The device can be incorporated into a cooking appliance which includes at least two heating elements (22, 24) defining separate heating areas for the cooking appliance. <IMAGE>

Title: Magnetostrictive material
Inventor: GIBBS MICHAEL RICHARD JOHN
IPC: H01L41/20
Filed: 1992-12-09
Granted: 1995-02-22
Abstract: A magnetic material of at least two component parts arranged to have respective structures which mutually are not homogenous, the structure of one part cooperating with the structure of the other to assist the magnetostrictive behaviour of the material. The cooperation can be the structure of one part altering the atomic spacing of the other part [Fig. 1 Fig. 2] and the alteration can be an increase from the usual atomic spacing. A layer may have a lattice structure modified by an overlaid layer. The modification may be that the lattice of the second layer adopts at least approximately the lattice of the first layer. There can be contiguous component parts and the cooperation can be a pseudo free surface on at least one said part or a reduced restriction of the local moment otherwise achieved by the contiguous component parts [Fig. 5]. Reduction in the thickness of the layers has the effect of making the magnetorestriction more positive whilst annealing of the composite structure will also cause an increase of the magnetorestriction indicating that the metals of the layers, eg Fe and Co, have alloyed. A component can be at least partly an alloy and the alloy can have ratio other than the usual one for said alloy. One of the components can be non-magnetic eg Al, Mg, Ag, Au or SiO* subscript minus * or both can be magnetic eg Fe, Ni, Co, Gd, Tb.

Title: Slip ring type shaft seal
Inventor: VAHTERI MATTI
IPC: F16J/
Filed: 1982-07-06
Granted: 1987-02-25
Abstract: The seal assembly comprises a slipring rotating with a shaft and includes sealing faces on both sides, against which stationary sealing rings are spring-loaded. The spring bears against only one of the rings. It is designed to press it against the slipring and the slipring is thus pressed against the other sealing ring. The slipring slides on the shaft in the axial direction. The design is particularly for use with immersion pumps. It is designed to separate the liq. handled, the oil, and the motor air chamber from each other.

Title: Double flange seal for heat exchanger tubes - is formed by two rubber rings in grooves formed by shoulders and recesses inside
IPC: F28C/
Filed: 1977-01-19
Granted: 1986-01-20
Abstract: Double flange-joint seal for the floating tube of a heat exchanger seals the tube wall from the jacket space and on the other side from the tube interior. The seal consists of two rubber rings (13) designed to fit into the space between the tube surface (3) or wall shoulder (4) and ring grooves (11, 12). The grooves are produced in the assembled and screw-tightened (8) joint inside the flange by expanding recesses in the jacket flange (5) round the inside of the joint assisted by recesses in the exchanger lid (7) flange (6). The grooves are completed by a shoulder (10) tapering inwards on a flange spacer ring (9). The end face of this ring terminates on the inside surface of the flange joint in the area of the cylindrical top face of the floating exchanger tube (3) wall or its shoulder (4). The endface of the groove forming shoulder (10) divide the upper of the two sealed ring grooves (11) from the lower groove (12).

Title: System and circuit for recursive digital filtering by the implementation of digital wave filters with a pseudo- symmetrical bilateral structure
Inventor: COPPOLA GIUSEPPE
IPC: H03K/
Filed: 1990-12-10
Granted: 1994-07-08
Abstract: The system according to the invention for digital filtering by the implementation of digital wave filters with a pseudo-symmetrical bilateral structure performs the function of filtering a digital signal in such a way as to minimize the effects due to arithmetic with finite precision caused by the limited length of the registers for data storage and processing. The particular structure, of the pseudo-symmetrical bilateral type, which is formed is essentially characterized in that it enables the critical path of the filter to be minimized and permits parallel processing of the two blocks of which it consists; thus, by using asynchronous data control, a highly efficient processing structure is obtained, which has a low processing time and is suitable for the multiplexing of the storage and multiplication operations. A circuit for the embodiment of the invention in the simplest and most general form consists of a suitable connection of adders, multipliers and delay elements. <IMAGE>

Title: Binding machine for bales of paper etc. - uses rotating device to twist two knots in wires at each end of bale
IPC: B65B/
Filed: 1974-09-04
Granted: 1980-11-20
Abstract: The machine ties two knots at the same time, one behind a bale, the other in front of the following bale. The device has two pairs of concave members (1a, 1b, 2a, 2b) which are pushed towards each other between bales, drawing the wires (F) in towards the centre. Two half wheels (7a, 7b) are thus brought together, and are made to rotate by a drive belt system. The two halves (10a, 10b) of a cross-bar also rotate, twisting knots on either side of the device. The half wheels are then returned to a position allowing the separation of the elements, and the ring formed in the wires is used as a point to cut the wires and separate the bales.
